Technical information

The MOON LP 5.3 represents a significant step forward in phono preamplifier design. Particular attention has been paid to noise levels and dynamic range, making the LP 5.3 one of the quietest phono pream- plifiers ever, on par and even superior to many models at significantly higher price points. Sonically, it portrays all

the Simaudio hallmarks: clean, powerful, fast and extended bass combined with an open midrange and airy extended high frequencies. One of the strengths of the LP 5.3 is its extensive flexibility with

respect to end-user adjustments. The balanced outputs allows you to take full advantage of connectivity to a balanced preamplifier or inte- grated amplifier for a significant improvement in noise floor, dynamics and midrange transparency. Unlike most of the competition, which either uses mass-manufacturing tech- niques or a circuit mounted in a basic folded metal box, the LP 5.3 is housed in a custom-made, sturdy chassis with a 3/8”

brushed and anodized front panel.

MOON P5.3 Preamplifier Significant Design Features:

End-user adjustments for capacitance loading, resistance loading and gain level to extract exceptional performance from virtually all high quality phono cartridges • End-user adjustments to alternate between the RIAA and IEC equalization curves • Isolated and shielded power supply on a separate circuit board based around an ultra-low noise toroidal transformer • An extremely short signal path for a faster transient response

Single-ended RCA and balanced XLR output connectors • Optional external power supply • Power supply voltage regulation includes i2DCf (Independent Inductive DC Filtering) derived from the Evolution Series for increased dynamic range • Four-layer PCB tracings with dedicated ground and power planes using pure copper for low impedance characteristics. The advantages are better circuit layouts resulting in much shorter signal paths and a vastly improved signal-to-noise ratio • Rigid chassis construction to minimize the effects of external vibrations • A symmetrical circuit design with accurate matching of the very finest high quality electronic components • Designed to be powered up at all times for optimal performance

Low operating temperature for a longer than normal life expectancy.
